how? to turn this code into a part.touched code

Don't use the guys above me, his has some problems.

Edit: Don't worry about the tabs. The site has some problems with the formation of code.

local ToolName = game.ServerStorage.Keycard.Name
local door = script.parent

door.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
            if Player.Backpack:FindFirstChild(ToolName) then 
                print("Player has tool in backpack!") 
            else 
                print("Player does not have tool in backpack!")
            end
    end
end)

Next time please use the code boxes please. Thank you! Paste this in to your door part.

Some security stuff

Put the Keycard in serverstorage so it cannot be hacked / stolen

local ToolName = game.ServerStorage.Keycard.Name
local door = script.parent

door.Touched:Connect(function(Player)
    if Player.Backpack:FindFirstChild(ToolName) then 
        print("Player has tool in backpack!") 
    else 
        print("Player does not have tool in backpack!")
    end
end)
